1 Claim.

This invention relates to new and useful improvement in inner soles forshoes.

The object of the invention is to provide a simple, durable, cheap,washable inner sole which can be readily inserted into and removed froma shoe and which is sufficiently repellent to moisture so that the feetof the wearer will not be wetted even though the wearer has to walk onwet pavements.

A further object is to provide a simple and efficient constructionwhereby the sole may be easily and effectively inserted into the shoeand held securely in place and yet may be readily drawn out to dry, orentirely removed to wash when desired.

Further and more specific objects, features and advantages will moreclearly appear from a consideration of the detailed specificationhereinafter set forth, especially when taken in connection with theaccompanying drawings which illustrate a present preferred form whichthe invention may assume and which forms part of the specification.

In brief and general terms, the invention comprises an inner soleelement, preferably made of a mesh type knitted or woven fabric havingwater-repellent characteristics which permits the air to circulatefreely within the shoe to dry the leather inner sole beneath the meshfabric. The inner sole is provided with bound edges and, preferablytreated in any well known manner to stiffen it. This material isnaturally of a nature to resist the passage of moisture through it andtherefore, when placed in the shoe, acts as an effective barrier betweenthe sole of the shoe and foot of the wearer to moisture which may havepassed through the sole from Walking on wet pavements.

In order to easily and quickly secure this sole in the shoe, there isprovided a strip of cloth or other material with adhesive on both sideswhich is attached to the inner sole near the rear end thereof. One faceof the strip is therefore adhered to the inner sole and the other faceadheres to the leather inner sole of the shoe to hold the auxiliaryadded inner sole in place.

Preferably, the improved inner sole is marketed with the adhesive stripadhered to the rear end and the exposed surface covered with paper toprotect it until the sole is to be inserted into the shoe, when thepaper protective covering may be removed.

The preferred form which the invention may assume is shown in the draw gof whic Fig. 1 is a bottom plan view of the improved sole with theadhesive strip attached;

Fig. 2 is a side elevation thereof;

Fig. 3 is a detail enlarged section of a rear portion of a shoe showingthe improved sole in place; and,

Fig. 4 is a perspective view of the adhesive strip unit as it is madeand presented before it is attached to the inner sole.

Referring now merely to the specific form in which the invention isherein illustrated, it will be seen that I have provided an inner soleH] (see Fig. 1) made preferably of a mesh type fabric havingwater-repellent characteristics with the outer periphery H (see Fig. 1)bound in any desired manner. This material also is preferably treated inany suitable manner to stiffen it. The material of the above nature, ofwhich Nylon cloth is an example, has a, natural resistance to thepassage of moisture through it, and therefore, when used as an innersole will successfully resist the passage of moisture to the foot of thewearer which may have seeped through the leather sole of the shoe whenthe wearer has had to walk on wet ground. This construction will permitpowder readily to be inserted in the shoe below the inner sole whendesired. Nylon is to be defined herein as a thermoplastic long chainsuper polyamide having the general structural formula where a: and y areintegers of 1 or greater.

The inner sole is of course shaped in many forms to conform to whatevertype or size of shoe it is to be associated with. In order to permit itto be easily and practically disposed and maintained in proper positionwithin the shoe, I provide a strip l2 (see Fig. 3) of material to beapplied to the heel portion of the inner sole and, although smaller, ofsomewhat the same general shape. This strip is provided with doublefaced adhesive coatings so that one face may be adhered to the innersole, and the other may be adhered to the heel portion of the shoe. Thisstrip of course is applied to the heel portion of the inner sole on thelower face thereof as shown.

Commercially, this strip portion may be separately made and sold withthe inner sole and when so presented, it has its double faces coveredwith suitable protective material such as paper i l (see Fig. 4), orother suitable substances, to cover the adhesive until the strip is tobe put into use. Sometimes, the inner soles may be sold with the stripattached to the underheel portion thereof in which case its lower facemay still have the protective cover 14 thereon until the sole is to beinserted into a shoe when the protective covering may be removed toexpose the adhesive coating to be adhered to the leather heel portionwithin the shoe.

It will be noted in Figs. 1 and 4 that the protective covering for thebottom side of the strip I2 is formed of two separate portions 14' andI4 which separately adhere to the lower layer 13 of adhesive. Thisparticular construction will permit the heel portion with the strip asshown in Fig. 1 to be gripped in the handuand. bent around the dividingline between the strips so that the finger may be more readilyinsertedto turn up the edge of each section as, shown in Fig. 4 tofacilitate the removal ofthe upper cover sections when the inner sole isto be inserteddn the shoe.

It is obvious .that this device is extremely simple andeffective,practical anduseful, and that it may be made easily andeconomically by modern mass production methods at a very low .cost. Atthe end of a day, the forward portion of the inner sole may be pulledout of the shoe to dry without totally disconnecting the rear portion.But if it is desired to wash the inner sole, the entire body of it maybe removed. When this is done, it will be found that the strip portion.l2 will remain in the shoe since it will stick more firmly to the heelportion of the shoe than it will to the lower face of the inner .sole.This feature will permit the inner .sole to be removed and washed andthen quickly and easily reinserted into the shoe so that its heelportion will again be adhesively .pressedagainst the upper face of thestrip 12.

Therefore, the. invention presents a simple, cheap, effective devicewhich has been proved in practice to permit a person to walk along wetpavements without getting his feet wet. due to the resistance tomoisture passage of the cloth.

While the invention has beendescribed in detail, and shown with respectto the accompanying drawing, it is not tobe limited to such de- '4tails, since many changes and modifications may be made in the inventionwithout departing from the spirit and scope thereof. Hence, it isdesired to cover any and all forms and modifications of the inventionwhich may come within the language and scope of the appended claim.

I claim:

An inner sole adapted for insertion in shoes and formed of stiffenedmoisture resistant cloth having bound edges, a strip of materialadhesively attached to the heel portion of the sole on its lower face,the lower surface of the strip having an adhesive coating and beingcovered .by., a removable layer of protective paper material formed intwo spaced sections with a dividing line therebetween extendinglongitudinally of the inner sole, said lower surface of the strip ofmaterial adapted to attach itself to the inner heel portion of a shoe,and said inner sole adapted to be detached from said strip of materialfor washing purposes.
